Question

If $n open parentheses A close parentheses equals 4 comma blank n open parentheses B close parentheses equals 3 comma blank n open parentheses A cross times B cross times C close parentheses equals 240$ , then $n left parenthesis C right parenthesis$ is equal to

288
1
12
2

The correct answer is: 2

$because blank n open parentheses A cross times B cross times C close parentheses equals n left parenthesis A right parenthesis cross times n left parenthesis B right parenthesis cross times n left parenthesis C right parenthesis$
$therefore n open parentheses C close parentheses equals fraction numerator 24 over denominator 4 cross times 3 end fraction equals 2$
